BEST ANSWER:Some sort of steel. Not sure of the grade. So far, so good. I bought these for a race car trailer and so far with the wonderful roads we have in CA., none have fallen apart yet! But I did buy spares just in case.

BEST ANSWER:Did install these, but am not familiar with the bulldog term. IMO these are only for doors that will only be used infrequently. It has a high pullout strength and will likely last a long time, but they are very loud and sometimes drag a bit taking a careful second or third push. I put one on a full size luan interior door and one of these small units did work which tells you how strong these are. Good luck on you ap.

Used these to hold a blank kitchen cabinet panel in place. New oven didn't quite fill the hole left by previous appliance and had to make a blank panel to cover the hole (looks like a drawer but no handles). These worked perfectly...just have to be very careful when measuring. Beat the heck out of driving nails through the panel and the blank panel pops right off if I ever need it to. Seems to hold pretty solidly...my dog ran into the panel and it didn't budge.

It does what I need it to do. We have a race car trailer and I knew we were going to break a few going down the road. But I have spares and at the price and time it takes to replace the plastic circle part that fails, it makes it a lot easier. Really holds the cabinet doors tightly. The ones that have broken still held the cabinet door in place until we opened so that was good. I'm happy for this inexpensive product that you can't see from the outside. I would recommend definitely.

I installed these on my kitchen cabinets to help prevent damages caused by living in California earthquake country. For the most part, these catches work pretty well for nominal quakes and have prevented my cupboards from opening. I must still excercise caution caution in opening cabinets after a quake to avoid things falling out. The only negative thing I have to say about these catches is that after repeated use, they tend to break. It seems the plastic housing held in place by a metal retaining ring on the female catch starts to crack and eventually falls out of the metal holder. But I store up on these and replace as necessary. It's a lot cheaper than buying new dishes.
